3. Kelce isn't K.C.'s only mystery man at tight end. Coach Andy Reid is thrilled with the progress of former basketball player Demetrius Harris. The 6-foot-7, 230-pound target from Wisconsin-Milwaukee was eligible for the team's rookie camp after failing to record a snap last season. "I thought he played exceptionally well," Reid said. "He's so big and he's worked so stinking hard in the weight room, he's been living in there with (strength and conditioning coach) Barry (Rubin) this offseason and you can tell. You can see he's gotten stronger."

5. Reggie Wayne is ahead of schedule in his return from last year's season-ending knee surgery, but Colts beat writer Mike Wells of ESPN.com doesn't expect the veteran wideout to participate in Indy's mandatory minicamp next month. Wayne should be full-go by training camp.

6. Don't plan on seeing Henry Melton, either, when the Cowboys open OTAs on Tuesday. Coming off last year's ACL surgery, the defensive tackle is penciled in to make his debut at training camp in July, according to the team's official website. While the 3 technique is a no-go this week, Dallas does expect two of last year's walking wounded -- linebacker Sean Lee and running back Lance Dunbar -- to join in OTAs.
